In the existing various energy power generation modes, thermal power generation utilizes the heat energy generated by combustion of combustible materials such as coal, petroleum, natural gas and the like to change water into high-temperature and high-pressure steam, and drives a power generation power device to convert the steam into electric energy; but the energy consumption is large, the heat energy utilization rate can only reach 60-70%, the fossil fuel resource is less and less due to the need of consuming fuel, even the fossil fuel resource can be exhausted, and simultaneously, a large amount of carbon dioxide can be discharged to pollute the environment, so that the sustainable development requirement is not met.

Although hydroelectric power generation is pollution-free, the investment of fixed assets is large, the requirements on the geographical environment are high, and the position limitation is large. Wind power generation utilizes kinetic energy of wind to generate electricity, although wind energy is renewable energy, the wind energy has uncertainty due to large and small wind volume, and the electricity generation is unstable; meanwhile, if the wind power plant is built on the bird migration way, the birds can be damaged, the noise of the wind power plant is high, and the noise influences on residents close to the wind power plant. The investment cost of nuclear power generation is too high, and a large amount of radioactive substances are released to the external environment in an accident, so that the ecological environment and the public are harmed.

Some semi-closed spaces (communicated with the outside through air pipelines) need to be built on the shore, and the rise and fall of sea waves cause the change of air pressure in the spaces, so that air in the pipelines flows in and out, a turbine is driven to rotate, and a generator is driven to generate electricity.
